Decreasing availability of water and increasing consumption of it in recent years shows water management plans increase its value. Depending on water consumption in the current and previous years, it is important to predict water consumption in the coming years and make plans accordingly. Evaluation of the performance of water use in agriculture, identifying water resources that are most intensively used and prediction of the potential performance in the coming years have become increasingly important.

Rice is commonly grown by transplanting one month-old seedlings into puddled and continuously flooded soil which leads to higher losses of water through puddling, surface evaporation and percolation. Excessive pumping of water for puddling causes problems of declining water table and poor quality water for irrigation.

Geoinformatics is application of information technology for study and management of earth resources. The salt affected soils of Gohana were mapped and evaluated using visual interpretation of IRS-P6 satellite false colour composite (FCC) image with ground survey and laboratory analysis. A total of 72 soil samples across the study area were sampled based on the quality of groundwater used for irrigation at four depths (0-15, 15-30, 30-45 and 45-60 cm). Long-term irrigation with salt affected water results in soil quality decline.

In the present study, diagnostic analysis of the irrigation system was done and a rotational water allocation plan on the basis of ET requirement of crops was developed for a command area. The crop water requirements for the major Rabi crops viz. wheat, gram and barley were computed by Penman-Monteith method using computer program ‘CROPWAT’ and these were used in the development of rotational water allocation plan. This system leads to increased credibility and reliability, enhanced equity in water distribution, proper utilization of water resources and increased water use efficiency.
